Next layer of my safespace box. The front is grid of old keys forge-welded onto sheet steel. These all depress to touch, but one releases another key, allowing access to a hidden functional key. A pull ring releases the key covering another space containing a lock. This extends a pin that will lock this layer in the final multilayered box. The three true keys to this layer of the search for self knowledge cannot be readily identified amid the false keys, as is true of real life. I am having fun with this, though I have not noticed any increase in wisdom.
